Green Mountains Nature Reserve, Quebec

Most places under NCC's care welcome visitors. Please check site-specific pages on this website for access information and any special restrictions.

The Nature Conservancy of Canada’s (NCC's) Green Mountains Nature Reserve, located 90 minutes from Montreal and covering 7,000 hectares, is an ecological gem in the Eastern Townships. It is one of the most important connectivity zones in the Appalachian chain, which extends from the American state of Georgia through Quebec to Newfoundland.

Here visitors can marvel at the myriad of ecosystems which provides habitat for large mammals such as black bear, moose and bobcat. A variety of trees make up the forests covering the mountains, including beech, ash and maple which dominate the deciduous forest, and at the highest altitude, fir, spruce and birch characteristic of mixed-wood forests. Google Trekker has covered an 11-kilometre segment of the Green Mountains trail.

NCC, in collaboration with the Parc d’environnement naturel de Sutton (PENS) and the Town of Sutton, is intensifying efforts to prohibit walking dogs off-leash on trails managed by PENS within the Green Mountains Nature Reserve. Informational signs have recently been installed, and park rangers have been recruited to ensure compliance with municipal regulations. To learn more about the current rules, please visit the PENS website.

Dogs are strictly prohibited, even on a leash, on the trails at the Green Mountains Nature Reserve. Leashed dogs are allowed only PENS-managed trails outside of the Green Mountains Nature Reserve. Please inquire before planning your visit. Thank you for your cooperation in protecting the integrity of this exceptional natural environment.
